Oil pump control method and device and oil pump

The invention discloses an oil pump control method and device and an oil pump. The method comprises the following steps of calculating target flow of the oil pump according to rotating speed of a steering wheel; calculating target displacement of the oil pump according to rotating speed of an engine and the target flow; and adjusting eccentric distance of the oil pump according to the target displacement, thus making the actual displacement of the oil pump reach the target displacement. According to the oil pump control method and device and the oil pump, the displacement of the oil pump can be adjusted according to the rotating speed of the engine and the rotating speed of the steering wheel, and therefore the displacement of the oil pump can be increased to reduce the oil temperature ofa system when a vehicle is in the idle state and the steering wheel rotates. 本发明提出了一种油泵的控制方法、装置及油泵，包括：根据方向盘的转速计算得到油泵的目标流量；根据发动机的转速和所述目标流量计算得到所述油泵的目标排量；根据所述目标排量调整所述油泵的偏心距，以使所述油泵的实际排量达到所述目标排量。根据本发明实施例的一种油泵的控制方法、装置及油泵，可使油泵的排量除了可
